NMEA 2000 Fast Packet errors
Hi everyone. I have an intermittent problem with fast packet errors on my NMEA 2000 network fed by SignalK. I’m running SignalK on a Pi with a Yacht Devices YDNU-2 USB to NMEA2K adapter. Occasionally (most of the time, but not always) when I reboot the Pi my B&G plotter will show some of the SignalK data missing. I can look at the network diagnostics on the plotter and see the “fast packet error” count increasing by a few packets per second. Then I need to go into SignalK, disable the SignalK to NMEA2000 and B&G Performance plugins and restart SignalK. As SignalK restarts the Fast Packet Error count stops increasing. Then I can reenable the plugins and everything works fine with all data available. Has anyone seen anything like this?

First I have heard of it. Can you narrow it down? Is it the sk-to-n2k plugin or the B&G plugin that is the issue?
It seems like I need to disable both plugins for the errors to reliably go away. I don’t reboot often so I don’t have too many test runs to try different combinations though.
